No official confirmation or comment from Ubisoft though. But the article also reports that there will rideable elephants in the game!
The game is being planned to be released in March 2015 and an official announcement will most likely be made in E3 this year. It will also undoubtedly be on next-gen consoles & PC but not sure about current-gen consoles.
I knew a Far Cry 4 would be coming, after the success of FC3 and Far Cry: Blood Dragon but didn't expect it to be that fast. I heard a lot of good reviews about those so I'll be checking them out before Far Cry 4 is out.
Who's excited to ride elephants?!
